Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747478, here are decompositions:

7 + 8747471 = 8747478
37 + 8747441 = 8747478
59 + 8747419 = 8747478
71 + 8747407 = 8747478
97 + 8747381 = 8747478
149 + 8747329 = 8747478
151 + 8747327 = 8747478
227 + 8747251 = 8747478

Showing the first eight; more decompositions exist.
